Description

Technical Field

[0001] The utility model relates to the technical field of particle preparation, in particular to a micro-pill extrusion and spheronization machine. Background Art

[0002] The pellet extrusion and spheronization machine is a device specially used to convert powder or granular raw materials into pellets or granules of uniform size and regular shape through extrusion and spheronization processes. The machine usually consists of two parts: an extruder and a spheronization machine. The extruder is responsible for extruding the raw materials through a screw, while the spheronization machine is responsible for spheronizing the extruded particles to form regular pellets or particles. The working principle of the pellet extrusion and spheronization machine is to heat and extrude the raw materials through the extruder to form particles with a certain shape, and then spheronize them through the drum or roller of the spheronization machine to form uniform spherical or cylindrical pellets.

[0003] At present, when the micro-pellet extrusion and spheronization machine is in use, some materials themselves have high viscosity or contain sticky components, which may cause the materials to easily adhere to the inner wall of the equipment during the extrusion and spheronization process. The long-term accumulation of materials on the inner wall of the equipment may form dirt that is difficult to remove, requiring more time and effort to clean, increasing the downtime and maintenance costs in the production process; therefore, it does not meet the existing needs, and we propose a micro-pellet extrusion and spheronization machine.
